ABSTRACT:
An on-location sewage treatment apparatus comprises a tank and a cylindrical wall therein arranged to form therewith a plurality of series-connected pre-treatment compartments. A grinder receives and grinds sewage-containing liquid and introduces same in the form of a colloidal mixture into a first of the pre-treatment compartments. The colloidal mixture gravitates between the pre-treatment compartments, the waste matter being aerobically consumed by bacteria therein. A second cylindrical wall spaced inwardly of the first endless wall forms therewith an intensive treatment compartment which receives pre-treated liquid. An upright porous sheet in the intensive treatment compartment is arranged in a circular accordian-pleated configuration. The sheet supports a bacteria culture thereon which consumes waste matter in the mixture passing through the sheet. Pure oxygen gas is introduced into each of the compartments and includes a sound wave generator for dispersing the oxygen gas. A third cylindrical porous wall disposed within the second wall defines a disinfecting compartment. Ozone gas is introduced into the disinfecting compartment to disinfect the liquid. Pure oxygen formed as a reaction product in the disinfecting compartment is collected and conducted back to the previous compartments.
